An amazing bike I've never heard of... An Ace Polini tuned V2 Simson.

Wow.... just plain freaking WOW! I've never even heard of this bike. what an amazing little machine!

From Hagen Schroot:Hello,
here are some pictures and videos from an Simson S51 V2 with 50HP.
The Simson S51 is 50ccm motocycle with 3,6 HP stock bulid in East Germany in 1980`s.
This Simson is the personal ride from an famous exhaust manufacturer for the Simson scene.
At the moment is only 120km/h fast, because of the brakes , but lift up the front in 5tgh gear!

Actualy each of the cylinders has 94cc which adds a total of 188cc. The Bore is 52mm and the stroke is 44mm. Cylinders are called "Polini Big Evolution" for modern Motor Scoots. Carbs are two 28mm Stage6 PWK (a decent copy of the Keihin PWK)

In the link below you can see the dynojet (Ammerschlaeger P4) protocol. The blue curve is the one of this engine. The other one is just for comparison to a 130cc single cylinder engine.http://www.bitsau.de/1/polini/motorklein.jpg
